Microsoft has issued an out-of-band update to fix an issue with Windows devices with Arm chips that was caused when users applied their June 2022 Patch Tuesday updates. The issue caused problems signing into Azure Active Directory and Microsoft 365 on Arm devices, and also affected applications and services that use Azure Active Directory for signing in, such as Microsoft Outlook, OneDrive for Business, and Microsoft Teams
Microsoft has rolled out the update, which will be installed automatically via Windows Update, although the update can be manually downloaded via the Microsoft Update Catalog. The update has been applied in KB5016139 for Windows 10 and KB5016138 for Windows 11.
Microsoft explained that the updates are cumulative, so there is no need to also install the June 14, 2022, update if it hasn’t been installed already, just skip that update and install the latest one instead. If for any reason the update cannot be applied, Microsoft said OneDrive, Teams, and Outlook can still be accessed without issue using the web-based versions of the products.
That was not the only issue with this month’s updates. Some users reported problems connecting to Wi-Fi networks using the Wi-Fi hotspot feature after applying the Patch Tuesday updates. Users also reported issues with .NET Framework 3.5 apps, which prevented the apps from opening in some cases. Microsoft said the issue only affected apps that use optional components, such as Windows Communication Foundation (WCF) and the Windows Workflow (WWF) component. That issue could be resolved by re-enabling .NET Framework 3.5 and the Windows Communication Foundation in Windows Features.
This latest bug will not instill confidence in the new automated patch service – Windows Autopatch – which is due to be launched next month. Rather than releasing Patch Tuesday updates, Windows 10/11 Enterprise E3 users will be able to take advantage of the automated patch service, which is billed as being released to take the pain out of applying updates to Windows. However, Enterprise E3 will still have the option of continuing to apply patches and updates manually.
